Rediscovering the Jansson & Hondius Atlases of Henry Vignaud
Atlantis Maioris Appendix of 1630
The Atlantis Maioris Appendix was published by Jan Jansson in 1630, but the edition owned by the University of Michigan Stephen S. Clark Library is an exclusive copy that was compiled after 1634. The Atlantis Maioris Appendix is composed of 80 maps, but the Vignaud Map Collection of the University of michigan Stephen S. Clark Library holds only 34 of them. At some point in the history of these maps, someone wrote manuscript numbers in the upper right hand corner of the verso. The sequence determined by the numbering matches the collations found in Peter van der Krogt's description in Koeman's Atlantes Neerlandici.
There is one map in the University of Michigan Stephen S. Clark Library's collection that makes this set of maps unique, Germaniae post omnes in hac forma editiones exactissima locupletissimaque descriptio, which was printed in 1634, implying that this particular group of maps was not produced and bound until somewhere after 1634. The inclusion of Germaniae post omnes... is not uncommon as atlases of the time varied significantly. Publishing houses would produce piles of specific maps, which would be compiled upon the request of a patron. When a certain map ran out, another of similar subject would replace it.
